CVE-2026-20212 is a critical vulnerability in Cisco NX-OS Software affecting the Silicon One integration for Cisco Nexus 9000 Series Switches. It allows an unauthenticated remote attacker to execute code with root privileges by connecting to TCP ports 43210 and 43211, which are accessible by default in the Layer 3 VRF. Exploitation can also cause the S1HAL process to crash, potentially leading to device reloads. Join the discussion | GCVE Database | 09/02/2026, 16:13:08 UTC Added: 09/03/2026, 15:16:38 UTC |
A vulnerability in the Silicon One integration for Cisco Nexus 9000 Series Switches could allow an unauthenticated, remote attacker to execute code with root privileges. This vulnerability exists because TCP ports 43210 and 43211 are accessible in the default Layer 3 (L3) virtual routing and forwarding (VRF). A successful exploit could allow the attacker to connect to an affected device and send crafted input that could be executed as code with root privileges. The exploitation of this vulnerability could also cause the S1HAL process to crash, which could cause the device to reload.
